AGC Switch
This button selects the AGC characteristics for the re-
ceiver. Available selections are FAST, MID, SLOW,
or AUTO, and the "AGC" icon will change according
to the AGC characteristics selected.
Press the [ AGC ] button repeatedly to select the de-
sired receiver-recovery time constant. Press and hold
in the [ AGC ] button for two seconds to disable the
AGC (for testing or weak-signal reception).
When the [ AGC ] button is pressed independently, it
applies to the Main band (VFO-A) receiver.
When you press the [ B ] button, followed by the [ AGC ]
button (within five seconds of pressing the [ B ] switch),
it affects the Sub band (VFO-B) receiver.

DVICE
If the AGC receiver-recovery time is set to "Off
pressing and holding in the [ AGC ] button, the S-meter
will no longer deflect. Additionally, you will likely en-
counter distortion on stronger signals, as the IF ampli-
fiers and the following stages are probably being over-
loaded.
NB Switch
This button turns the IF Noise Blanker on and off.
Press this button momentarily to reduce a short-dura-
tion pulse noise; the "
play.
Press and hold in this button for one second to reduce
a longer-duration man-made pulse noise; the "
icon will blink for three seconds, then will appear con-
tinuously in the display.
Press this button again to disable the noise blanker;
the " " icon will disappear.

DVICE
When you press (or press and hold) the [ NB ] button
momentarily, it affects the Main band (VFO-A) re-
ceiver. When you press the [ B ] button, then press (or
press and hold in) the [ NB ] button (within five sec-
onds of pressing the [ B ] button), it affects the Sub band
(VFO-B) receiver.
METER Switch
This control switch determines the function of the meter
during transmission.
COMP: Indicates the speech compressor level (SSB
mode only).
ALC: Indicates the relative ALC voltage.
PO: Indicates the average power output level.
SWR: Indicates the Standing Wave Ratio (Forward:
Reflected).
ID: Indicates the final amplifier drain current.
VDD: Indicates the final amplifier drain voltage.

MONI PROC Knobs
MONI Knob
The inner [ MONI ] knob adjust the audio level of the
transmit RF monitor during transmission (relative to
the AF GAIN control), when activated by the [ MONI ]
button.
PROC Knob
The outer [ PROC ] knob sets the compression (input)
level of the transmitter RF Speech Processor in the SSB
and AM modes, when activated by the [ PROC ] but-
ton.
BK-IN Switch
This button turns the CW break-in capability on and
off. While the CW break-in is activated, the "
icon appears in the display.
SPOT Switch
This button turns on the CW receiver spotting tone; by
matching the SPOT tone to that of the incoming CW
signal (precisely the same pitch), you will be "zero
beating" your transmitted signal on to the frequency of
the other station.
The Sub (VFO-B) frequency display will indicate the
offset tone frequency when this button is pressed.
SPEED PITCH Knobs
SPEED Knob
The inner [ SPEED ] knob adjusts the keying speed of
"
the internal CW keyer (4 ~ 60 WPM). Clockwise rota-
tion increases the sending speed.
When turning this knob while pressing the [ KEYER ]
button, the Sub (VFO-B) frequency display shows the
keying speed.
PITCH Knob
The outer [ PITCH ] knob selects your preferred CW
tone pitch (from 300 ~ 1050 Hz, in 50 Hz increments).
The Tx sidetone, receiver IF passband, and display
offset from the BFO (carrier) frequency are all affected
simultaneously. The Pitch control setting also affects
the operation of the CW Tuning Indicator, as the cen-
ter frequency of the CW Tuning Indicator will follow
the setting of this control.
NB SQL Knobs
NB Knob
The inner [ NB ] knob adjusts the noise blanking level
when the (analog) IF noise blanker is activated by press-
ing the [ NB ] button.
SQL Knob
The outer [ SQL ] knob sets the signal level threshold
at which the Main (VFO-A) receiver audio is muted,
in all modes. It is very useful during local rag-chews,
to eliminate noise between incoming transmissions.
This control is normally kept fully counter-clockwise
(off), except when scanning and during FM operation.
